Poly Mailers

Poly mailers for clothing, soft goods and everyday shipping

Shop poly mailers by listed size, material thickness, closure and case count. For folded clothing and other non-fragile items, a mailer can be a practical alternative to a carton. Start with the packed item: its width, length and thickness determine the size you need. Then compare white, clear-view or black poly mailers and select a case quantity that fits your order volume.

The 10x13 poly mailers below are three specific starting points. Their listed dimensions are not a guarantee of usable interior space: allow room for the item's thickness and the adhesive closure, and test the fit before committing to a larger order.

Compare 10x13 poly mailers

Selected 10x13 self-seal poly mailers
Product and SKU Listed size Thickness and closure Case count
Black poly mailers — CPM1013BK 10 x 13 in 2.5 mil, self-seal 100 mailers
Clear-view poly mailers — CV1013100PK 10 x 13 in 2.5 mil, self-seal 100 mailers
Clear-view poly mailers — CV1013 10 x 13 in 2.5 mil, self-seal 500 mailers

The two clear-view examples have the same listed size and thickness but different case quantities. Compare the exact SKU and case count when reordering; a similar product name does not establish the same pack quantity.

Use each row's dimensions, format and count to compare these options. An expansion mailer adds depth to its listed format; check its specific dimensions instead of treating it as interchangeable with a flat mailer. Black and clear-view options also serve different presentation needs.

Choose a mailer for the contents

Packaging choices to check before ordering
What you are packing Start with Check before buying
Folded clothing or soft accessories A flat self-seal poly mailer Packed thickness, fit and room to close the seal without forcing it
A bulkier soft item An expansion mailer The listed depth as well as width and length
An item whose appearance matters through the package A clear-view mailer The viewing area and a suitable label position
An item needing cushioning or crush protection A padded format or properly sized carton The complete protective packing method; plain poly film supplies no cushioning

Buying poly mailers in bulk

Build your order around the sizes you actually use. Keep separate counts for each SKU, and compare smaller and larger case packs using the same unit calculation. A larger case only helps if its contents fit your orders and you have room to store it.

For a multi-case order or recurring requirement, request a bulk quote with the SKUs, case quantities and delivery ZIP. Include your expected reorder frequency if known. If you are matching another supplier's packaging, the Uline poly mailer alternatives guide explains which specifications to compare.

Poly mailer questions

Will a 10x13 poly mailer fit my product?

Measure the item as it will ship, including folds and any inner packaging. Compare all dimensions and leave room for closure. A flat item's width and length alone cannot confirm the fit of a thicker item.

Are these examples self-seal?

Yes. All three linked 10x13 examples are listed as self-seal. Check the individual listing for closure details on other products, particularly when a return mailing is part of your process.

Should I choose a poly mailer or a padded mailer?

Plain poly mailers suit contents that do not need cushioning. Browse bubble mailers or padded mailers when padding is needed, and use a carton and appropriate protection when the contents need a rigid package.

Complete your packing setup with shipping labels and packing list envelopes, or browse the broader mailers and envelopes collection.

For larger white poly mailers, compare these exact listed dimensions and case counts with the 10x13 options above. A nominal 14.5x19 or expansion dimension is not a promise of usable space after the closure and packed-item thickness.

White self-seal formats for a separate fit check.
SKU Listed dimensions Listed film Mailers per case
B876100PK 14.5 × 19 in 2.5 mil; white 100
EPM20244 20 × 24 × 4 in; expansion format 2.5 mil; white 100

For 350 mailers of one selected 100-count format, four cases supply 400. Fit the actual contents with their packing, leave space for the closing flap and check a sample before replacing a current size. These unpadded poly mailers do not provide the cushioning of a bubble mailer or the rigidity of a corrugated carton.
